High Pressure Forged Steel Trunnion Ball Valve

A forged steel flanged high pressure ball valve in which the ball is rotated around the center line of the valve body to open and close, and the seal is embedded in the stainless steel valve seat.

The end of the metal seat is provided with a spring, when the sealing surface is worn or burned, under the action of the spring to push the seat and the ball to form a metal seal. It has a unique automatic pressure relief function,

When the medium pressure in the valve cavity exceeds the spring preload force, the outlet end valve seat is withdrawn from the ball to achieve automatic pressure relief effect, and the valve seat automatically resets after pressure relief, which is suitable for general working media such as water, solvent, acid and natural gas.

Moreover, it is also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc., which has been better applied in various industries.

Structure:

1. All parts of this high pressure forged steel ball valve are forged.

2, It adopt bottom-mounted valve stem, set the reverse seal structure, to ensure that the packing place reliable seal and prevent the valve stem out.

3, It adopt Mosaic valve seat. The O-ring is arranged behind the seat to ensure that the medium does not leak out.
